Oh, I love 3D......here I am using flowers of course. These are a little different from my usual flowers made from paper because they are punched from card stock, shaped and stuck to polystyrene balls. So you get this amazing round flower and it's very easy to construct.
I have embossed a piece of cream card and trimmed it to the size I want for my background. I have then cut in half (using a sharp craft knife) three polystyrene balls (Woodware FPC-Balls) and have stuck five halves to the embossed card using a good blob of PVA glue. Allow that to dry while you punch lots and lots of red (or blue) flowers from textured card using the Woodware punch 826-26 lilac blossom.
